When you attempt an Intimidate check to demoralize foes, you can forgo your expertise die to attempt to briefly demoralize a small group as a full action. You attempt an Intimidate check against foes within 60 feet, no two of which can be more than 20 feet apart. The DC of this check is equal to the highest DC to demoralize any one of the foes. If you are successful, the targets gain the shaken condition for 1 round (even if your result exceeded the DC by 5 or more). Once you use this ability against a creature, it is immune to this talent for 24 hours.
